PPH Foot Valve

A PPH Foot Valve is a type of non-return (check) valve made from Polypropylene Homopolymer (PPH) that is installed at the inlet (suction side) of a pump, usually at the bottom of a pipeline or submerged in a tank, to prevent backflow and keep the pump primed. A PPH foot valve is a valve with a built-in strainer and check mechanism that allows fluid to enter the pipeline from a tank or source while preventing reverse flow, and it is constructed from corrosion-resistant PPH material for use in chemical and water systems.

PPH foot valve is located at the end of a pipeline. In addition to serving as a check valve, these also include a strainer attached to the open end of the valve.The check valve has a spring-assisted check valve and PPH Piping Systems. Whenever a pump is turned on, the tension of the pump column changes, and the valve opens as a result. Whenever the pump is turned off, the PPH Foot Valve responds by closing once again. As a result, the pump will not lose prime every time it is turned off due to leakage of fluid from the pump column
